KolbeSchmittis

KolbeSchmittis refers to a class of chemical reactions and products derived from the Kolbe-Schmitt reaction. This reaction is a carboxylation process that involves the reaction of phenoxide salts with carbon dioxide under heat and pressure. The primary product is salicylic acid, a key ingredient in aspirin and various other pharmaceuticals and chemical intermediates. The reaction mechanism typically involves the electrophilic attack of carbon dioxide on the activated aromatic ring of the phenoxide. Variations of the Kolbe-Schmitt reaction exist, allowing for the synthesis of substituted salicylic acids and other aromatic carboxylic acids by altering the starting phenol or reaction conditions. These derivatives find applications in the production of dyes, polymers, and agrochemicals. The historical development of the Kolbe-Schmitt reaction, attributed to Hermann Kolbe and Rudolf Schmitt, laid the groundwork for industrial-scale production of salicylic acid and its analogues.
